Linear syringocystadenoma papilliferum: An uncommon event with a favorable prognosis
Frontal fibrosing alopecia: A multicenter review of 355 patients
Background: To our knowledge, there are no large multicenter studies concerning frontal fibrosing
alopecia (FFA) that could give clues about its pathogenesis and best treatment.
Objective: We sought to describe the epidemiology, comorbidities, clinical presentation, diagnostic
findings, and therapeutic choices in a large series of patients with FFA.
Methods: This retrospective multicenter study included patients given the diagnosis of FFA. Clinical
severity was classified based on the recession of the frontotemporal hairline.
Results: In all, 355 patients (343 women [49 premenopausal] and 12 men) with a mean age of 61 years (range
23-86) were included. Early menopause was detected in 49 patients (14%), whereas 46 (13%) had undergone
hysterectomy. Severe FFA was observed in 131 patients (37%). Independent factors associated with severe
FFA after multivariate analysis were: eyelash loss, facial papules, and body hair involvement. Eyebrow loss as
the initial clinical presentation was associated with mild forms. Antiandrogens such as finasteride and
dutasteride were used in 111 patients (31%), with improvement in 52 (47%) and stabilization in 59 (53%).
Limitations: The retrospective design is a limitation.
Conclusions: Eyelash loss, facial papules, and body hair involvement were associated with severe FFA.
Antiandrogens were the most useful treatment. ( J Am Acad Dermatol 2014;70:670-8.
Risk factors and rate of recurrence after Mohs surgery in basal cell and squamous cell carcinomas: a nationwide prospective cohort (REGESMOHS, Spanish Registry of Mohs Surgery)
Randomized studies to assess the efficacy of Mohs micrographic surgery in basal cell and squamous cell carcinomas are limited by methodological and ethical issues and a lack of long follow-up periods. This study presents the "real-life" results of a nationwide 7-years cohort on basal cell carcinoma and squamous cell carcinoma treated with Mohs micrographic surgery. A prospective cohort was conducted in 22 Spanish centres (from July 2013 to February 2020) and a multivariate analysis, including characteristics of patients, tumours, surgeries and follow-up, was performed. A total of 4,402 patients followed up for 12,111 patient-years for basal cell carcinoma, and 371 patients with 915 patient-years of follow-up for squamous cell carcinoma were recruited. Risk factors for recurrence included age, non-primary tumours and more stages or unfinished surgeries for both tumours, and immunosuppression for squamous cell carcinoma. Incidence rates of recurrence were 1.3 per 100 person-years for basal cell carcinoma (95% confidence interval 1.1-1.5) and 4.5 for squamous cell carcinoma (95% confidence interval 3.3-6.1), being constant over time (0-5 years). In conclusion, follow-up strategies should be equally intense for at least the first 5 years, with special attention paid to squamous cell carcinoma (especially in immunosuppressed patients), elderly patients, non-primary tumours, and those procedures requiring more stages, or unfinished surgeries
